| description | Power tools and in particular hand held power tools are increasingly relying on cordless rechargeable battery packs as a powering energy source. Such battery packs are preferably compact and lightweight, but still deliver relatively high current and voltage for powering the tool motor. Described is a lithium-polymer tool battery comprising: a housing selectively connectable to and supportable by a hand held power tool or a garden tool, a plurality of substantially flat battery cells stacked within the housing such that each cell is layered over or under an adjacent cell and a resiliently deformable substrate located between adjacent battery cells, wherein each battery cell has a lithium-polymer based chemistry and a nominal charged internal impedance of less than or equal to approximately 10 milliohms. A lithium-polymer battery powered tool utilising the lithium-polymer tool battery is also described. |
